9 Current Transformer (CT) Function

The Current Transformer (CT) function is used with the alarm output. When using a current transformer (CT) with
the controller, change the corresponding alarm output mode to mode 13 (alarm output set value is 13), then turn
to operation mode and set the current lower-limit and current upper-limit. You can set current alarm range
between 0.5A ~ 30A, display resolution is 0.1A and measure accuracy is +/- 0.5A.

10 EVENT Inputs Function

5

There are two optional event inputs (contact inputs) supported (EVENT1and EVENT2) in DTB series.
EVENT1: RUN/STOP operation can be executed by RUN/STOP parameters (Operation Mode) or via the

communication. User also can control RUN/STOP operation by EVENT 1 in DTB series. The control
output is ON if the circuit of EVENT 1 is open when the controller is operating. Otherwise, the
controller will stop output if the circuit of EVENT 1 is short or when the system parameter of the
controller is set to STOP mode.

EVENT2: DTB series allows user can switch two temperature setting value by changing the status (open/short) of

EVENT 2. Each temperature setting value has independent control parameters.

11 PID Program Control (Ramp/Soak Program Control)

Description of Function and Parameters Setting:

PID program control by 8 patterns (Pattern No. 0~7) is supported in DTB series. Each pattern contains 8 steps

(step No. 0 ~ 7), one Link Pattern parameter, one Cycle parameter and one Actual Step parameter.

Start Pattern :

is in operation mode and it is used to set the Start Pattern of PID program control (This

parameter appear in

mode only).

Steps : Include set point X and execution time T, these two parameters setting. The set point (SV) should reach

temperature X after the period of execution time T. If the set point is the same as the result of the previous
setting, then it is called Soak program control. If not, then it is called Ramp program control. Therefore,
PID program control is also called Ramp/Soak program control. The default of step No. 0 in this controller
is Soak program control. The controller will control the temperature (PV) to reach the set point X and then
keep the temperature at set point X. The period of execution time is time T which provided by step No. 0.

Link Pattern Parameter : For example, when set

to 2, it indicates that pattern No. 2 will execute next after

the execution of pattern No. 0. If set to

, it indicates the program will stop after executing the current

pattern and the temperature will keep at the set point of the last step.

Cycle Parameter : Additional execution cycle number. For example, when set

to 2, it indicates that pattern

No. 4 should execute twice in addition. Include origin one time execution, total execute three times.

Actual Step Parameter : Execution step number per pattern (can set to 0 ~ 7). For example, when set

to

2, it indicates that pattern No 7 will not execute other steps than step 0 to step2.

Execution : When

controlled at the set point before program hold. Select

again, then the program will restart and execute from step 0 of

again, then the program will follow the step

Valve Control:

When use valve control as output control, there are 2 Relay outputs for motor forward/reverse control, one (output

1) for valve open the other (output 2) for valve close. The output volume is controlled by valve open/close and it
can be set with feedback function enabled or disabled. When feedback is disabled, output 1 will keep output while
valve fully opens and output 2 will keep output while valve fully closes. But if feedback is enabled, please follow the
parameter setting for valve control as follows:

: Time for valve from full close to full open.
: Dead Band setting of valve. The value of current valve output minus previous one must be greater than

Dead Band value; otherwise, valve will remain OFF.

: Signal feedback setting, ON for enabling feedback and OFF for disabling feedback.

When
